'ENGINE EXHAUST.

Application filed April 29, 1925. Serial No. 26,768.

To all 'whom t may concern.'

Be it known that I, VVELFORD CLARENCE DIAL, a citizen of the United States, residing at Pueblo, in the county of Pueblo, State of Colo-rado, have invented certain new and useful'Improvements in Engine Exhausts, of which the following is a specication This invention relates in general to engine exhausts and is particularly designed to be used with the exhaust systems of internal combustion engines of the type used on automobiles.

The object of the invention is the provision of an engine exhaust ywhich embodies a cut-out that may be readily opened to permit theV gases to pass directly from the engine to the atmosphere, but in'which there is normally provided a complete and unbroken exhaust line so that the gases pass through the muffler ordinarily provided.

One of the principal objects 'of the invention resides in the provision of a simple, durable and practical means of the character specifiedwhich is easily operated by the driver of the automobile, whichk is not liable to get out of order, and which is comparatively inexpensive to manufacture and apply.

A further object is .the provision of device of this character which eliminates butterfly valves or other types of valves liable to become stuck by deposits of carbon or other deposits. n

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the 40 accompanying drawings forming a part ,of

this specification, and in which:

Figure 1 is a fragmentary view partly in section and partly in elevation showing y one embodiment of the invention,

Figure 2 is a view in section on the line 22 of Figure 3, and

Figure 3 is a view in section on the line 3-3 of Figure 2.

Referring to the drawings the numeral 1 designates the internal combustion engine ofan automobile, and the numeral 2 designates the licor boards of the body thereof. The engine 1 has an exhaust manifold 3 from which an exhaust conduit t leads. The

Vplatev) fastened to the floor boards 2. i The 'pipe 6 operates in a guidek 10 vdepending lrack 18, which operates through guides 19 exhaust conduit 4 includes a stationary section 5 suitably supported on the body of thee automobile, and a movable section 6 havingy ai-flexible pipe 7 connecting the same with the exhaust manifold. rlhe stationary section 5` is connected withthe 'muffler (not shown) which is ordinarily provided on an automobile. The sections 5 and 6 are rigid and maybe ordinary metallic piping. The adjacent ends of the sections v5 and 6 are beveled, as indicated at 5a and` 6 and are adapted to be telescoped. or nterfltted as clearly shown in Figure 2. lVhen so telescoped or interiitted there is provided a con tinuous unbroken exhaust line which leads from the engine through the muffler in the ordinary way. lVhen the section `6 is withdrawn from the section 5 andshifte'd later-V ally with respect thereto,v as shownin dot-` ted lines in Fig. 1'., the engine exhaustsdirectly to the atmosphere to provide al cutout.` l

As shown in Figures2 and 3 the pipe 5 may be suitably secured to a bracket, designated generally at 8, and secured to a supporting from the plate 9. p

Means is provided for moving the movable section 6 s0 as to withdraw thef same from the section 5 `'and then shift the same laterally with respect to the section 5 and to the position shown in dotted lines in Figure i y, 1- and such means- .preferably includes a shaft 12 rotatably supported in suitable bearings provided therefor in ai bracket 13 carried by the bracket 8.- A. U-shaped crank 14 is'y fixed to the shaftf12 and has ay pair of crank .arms 15 which straddle the rmovable section l6 and which are pivotally connected thereto, as by means of a pivot pin 16. l

Foot control'means is vprovided for turning the shaft 12 and comprises a pinion 17 fixed to the shaft 12 and meshing with a 100 and 2O provided in the brackets 13 and 8,

respectively, and which extends up above the floor boards 2. On the upper end of i the rack 18 a foot piece 21 is provided.

`The rack 18 is normally held in elevated position by means of a retractile coil spring 22 having one end connected, as at 23,7to the plate 9 and having its other end connected, as at 24, to the rack 18. By elevating the rack 18 the spring 22 biases the shaft l2 to such a position as to cause the sections 5 and 6 to be intertitted, as shown in Figure 2. y

For the purpose of releasably securing the rack 18 in depressed position, the rack is i provided with a notch 25 which provides a v, asinay be necessary to engage the shoulder i shoulder 26 engageable with the plate 9 to hold the Vrack depressed. rlhe guides in Which the rack operates are designed to permit such rocking movement of Jche rack Y Words to out out the muffler, the operator ofthe machine merely depresses the-rack 18 which rotates the pinion 17 and the shaft lia The 'crank armsl moveivith the shaft l2,

ne shown in Figure 2 When the sections and .6 are interiitted, the crank arms 15ers vertically disposed, Consequently, when the shaft l2'iirst' begins to move, Vthe section 6 .is moved approxinmtelvY axially and away :from the section 5. As the crank arms 15 continue to swing the vertical component ,of

their angular" motion increases and the horiaontal component of their angular motion decreases so that toward the end of their movement .they shift the movable section downwardly. or latmallv` ywith respect to the stationary section,- When the rack 18 is i released it islnoved upwardly by the action of the spring andthe movement of the crank aimsl. and section 6 is reversed to cause the sections 5 and 6 to again be interitted-r I cla-ini: Y
